Babbitt reported on the 23rd, November 23, 2019 Netease Future Conference opened in Hangzhou. At the "Blockchain + Entity Economy" forum held in the afternoon, Cai Liang, executive deputy director of Zhejiang University Blockchain Research Center and vice president of Zhejiang University Software College, said in the speech that China's supervision requires all use of blockchain services. Users need real-name system, all enterprises that carry out blockchain business need to be filed, and all operations in China must be regulated. The alliance chain can meet these requirements and can be explored under controllable conditions. He also pointed out that due to the decentralization and non-tamperability of the blockchain, the use of blockchain to disseminate information has great challenges for supervision.
